[0002] As a type of sensor, a temperature sensor relies on the inherent temperature properties of a substance to measure temperature signals. Sensors typically utilize various materials or components, such as thermocouples, semiconductors, and infrared radiation, to sense changes in temperature characteristics and convert these changes into electrical signals for output. Temperature sensors are widely used in various fields, including healthcare, food processing, metallurgy, and electronics. They are particularly common in the industrial sector, for example, to monitor temperature changes in real time during production to ensure quality and safety. Digital temperature sensors, on the other hand, utilize temperature-sensitive components and corresponding circuitry to convert the physical quantity of temperature into a digital value that can be directly read by data acquisition devices such as computers, PLCs, and intelligent instruments.

[0022] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] See also Figures 1-4 The present invention provides a miniaturized digital temperature sensor, including a storage tube 1. In this application, the storage tube 1 can be processed by lightweight and highly tough engineering plastics. A bin-out cover 2 is provided on the top of the storage tube 1. A rotating part 3 is provided on the bin-out cover 2 and the storage tube 1. A temperature sensor body 4 is provided in the storage tube 1. A digital display 41 electrically connected to the temperature sensor body 4 is fixedly connected to the outer surface of the storage tube 1. In this application, the digital display 41 can be electrically connected using a wire that passes through the storage tube 1 and is connected to the data output end of the temperature sensor body 4. Since the temperature sensor body 4 is arranged in the storage tube 1 for the extension and concealment of the detection end, the digital temperature sensor is combined with the digital display 41 and the temperature sensor body 4 in a split manner. While satisfying the storage and protection of the temperature sensor body 4, the demand for digital temperature display can be met.

[0024] The rotating part 3 includes a fixed block 31, which is fixedly connected to the outer surface of the storage tube 1. A bracket 32 is provided on the outside of the fixed block 31. A torsion spring shaft 33 is provided on the bracket 32 and the fixed block 31. The bracket 32 is rotatably connected to the fixed block 31 through the torsion spring shaft 33. The outlet cover 2 is fixedly connected to the bracket 32. The torsion spring shaft 33 is composed of a torsion spring provided on the shaft. The torsion spring can give the bracket 32 rotatably provided on the fixed block 31 a certain rotational resilience. The outlet cover 2 can be opened when the temperature sensor body 4 is extended, and can be closed when the temperature sensor body 4 is hidden.

[0025] A mounting ring 5 is fixedly connected to the temperature sensor body 4, and a pair of top cover rods 6 are fixedly connected to the mounting ring 5. The top cover rods 6 are movably connected to the outlet block cover 2. A gear range extender mechanism 7 is provided on the mounting ring 5 and the storage tube 1. A push rod 8 is provided on the gear range extender mechanism 7. The push rod 8 moves through the storage tube 1 and extends to the bottom position of the storage tube 1. A tensioning spring 9 is provided on the push rod 8. In this application, the connection between the push rod 8 and the storage tube 1 can be slidably connected through a linear bearing. In this setting, the two ends of the tensioning spring 9 respectively abut against the opposite surfaces of the extended push rod 8 and the storage tube 1. When the push rod 8 extends out of the storage tube 1, the tensioning spring 9 can be compressed. The compressed tensioning spring 9 can provide the push rod 8 with the ability to reset and rebound.

[0026] A slider 11 is fixedly connected to the mounting ring 5, and a guide rail 12 for the slider 11 to slide is fixedly connected to the inner wall of the storage tube 1. In this application, the slider 11 is arranged in a T-shaped structure, so that the slider 11 slides on the guide rail 12 in a linear manner. Therefore, the temperature sensor body 4 can move stably vertically in the storage tube 1.

[0027] A pair of top cover rods 6 are set with a height difference, that is, the top cover rod 6 close to the rotating part 3 is lower than the height of the other top cover rod 6. The advantage of this design is that the other top cover rod 6 can preferentially provide a lifting force to the outlet cover 2, so that the force point of the outlet cover 2 can rely on the rotating part 3 to perform an opening rotation action on the storage tube 1 until the temperature sensor body 4 protrudes from the top of the storage tube 1. Because the outlet cover 2 has the real-time rebound effect of the torsion spring shaft 33, a short top cover rod 6 can continue to support the outlet cover 2, so as to avoid the outlet cover 2 affecting the effectiveness of the temperature sensitive element of the temperature sensor body 4. In this application, the height of the top cover rod 6 should be higher than the height setting of the detection end of the temperature sensor body 4.

[0028] The gear range extender mechanism 7 includes a fixed rack 71, which is fixedly connected to the inner wall of the storage tube 1. A transmission gear 72 is meshed with the fixed rack 71, and a wheel frame 73 is rotatably connected to the transmission gear 72. A movable rack 74 is meshed with the transmission gear 72, and the movable rack 74 is fixedly connected to the mounting ring 5. The movement of the transmission gear 72 meshing with the fixed rack 71 can increase the moving stroke of the movable rack 74, so that the temperature sensor body 4 can be quickly protruded from the storage tube 1 or hidden in the storage tube 1 by inputting the minimum pushing stroke.

[0029] One end of the push rod 8 is fixedly connected to the wheel frame 73, and the outer surface of the push rod 8 is fixedly connected to the limiting ring 13. The limiting ring 13 is movably abutted against the bottom end of the inner wall of the storage tube 1. The setting of the limiting ring 13 can prevent the push rod 8 from separating from the storage tube 1. The push rod 8 of this application adopts a T-shaped structure, and the end face of its largest end can be easily pushed manually.

[0030] The outer surface of the storage tube 1 is fixedly connected with a handle 10. Since the storage tube 1 is made of lightweight and tough engineering plastic, and is used handheld with the handle 10, the entire miniaturized digital temperature sensor is convenient for handheld operation and meets the miniaturized design of the structure.

[0031] When the present invention is in use, a certain thrust is manually given to the push rod 8 to make the push rod 8 enter the storage tube 1, and the push rod 8 can mesh with the transmission gear 72 on the wheel frame 73 on the fixed rack 71 and move upward. Under the vertical sliding guide provided by the slider 11 for the temperature sensor body 4, the meshing and rotating transmission gear 72 can transmit the movable rack 74. The movement of the movable rack 74 can give the temperature sensor body 4 the effect of extended range movement. During this process, the top cover rod 6 on the mounting ring 5 can abut against the outlet block cover 2, so that the outlet block cover 2 can be tensioned and rotated under the connection of the rotating member 3, so that the temperature sensor body 4 can protrude from the top end of the storage tube 1, so as to utilize the temperature sensitive element at the end of the temperature sensor body 4 to measure the ambient temperature;

[0032] By utilizing the rebound force of the compression of the tensioning spring 9 and manually releasing the thrust of the push rod 8, the temperature sensor body 4 can be quickly moved into the storage tube 1 to be hidden. At the same time, since the top cover rod 6 is disconnected from the outlet block cover 2, the outlet block cover 2 can be reset by utilizing the torsion spring action of the torsion spring shaft 33 to seal the top of the storage tube 1. Therefore, the purpose is to achieve rapid hiding and protrusion of the temperature sensor body 4 on the storage tube 1. While satisfying the storage requirements of the temperature sensor body 4, it also gives the temperature sensor body 4 a certain degree of dust-proof and anti-fall structural protection.
